§ Mr. Sainsburyasked the Secretary of State for the Environment what percentage of urban residential areas are subject to smoke control orders.
§ Mr. Denis HowellIt is estimated that some 75 per cent. of those areas which the Committee on Air Pollution—the Beaver Committee—in the map annexed to its Interim Report of 1953—Cmnd. 9011—indicated as "black areas" are now subject to smoke control orders. No assessment for urban residential areas generally is available.
§ Mr. Sainsburyasked the Secretary of State for the Environment how many orders declaring a new smoke control area have been submitted to and approved by his Department in each of the last five financial years.
§ Mr. Denis HowellThe figures are as follows:
